JOINTLY OWNED UTILITY PLANT/COORDINATED SERVICES

Our Regulated Operating Subsidiaries have agreements with other utilities for the joint ownership of substation assets and transmission lines. We account for these jointly owned assets by recording property, plant and equipment for our percentage of ownership interest. Various agreements provide the authority for construction of capital improvements and the operating costs associated with the substations and lines. Generally, each party is responsible for the capital, operation and maintenance and other costs of these jointly owned facilities based upon each participant’s undivided ownership interest. Our Regulated Operating Subsidiaries’ participating share of expenses associated with these jointly held assets are primarily recorded within operation and maintenance expenses on our consolidated statement of operations.

We have investments in jointly owned utility assets as shown in the table below as of December 31, 2015:
